Abstract: Self illuminated back and front lit signage for a printed graphic. The signage includes a turning film having a structured surface for redirecting light, a diffuser providing for diffusion, and a printed graphic. The turning film receives light from an ambient light source and directs the light via the structured surface toward a viewer of the graphic in order to passively illuminate the signage.

Abstract: An optical article, such as a backlight for electronic display devices, is disclosed. The optical article includes a lightguide, a viscoelastic layer disposed on the light guide and a nanovoided polymeric layer disposed on the viscoelastic layer. The nanovoided polymeric layer comprises a plurality of interconnected nanovoids and at least some of the interconnected nanovoids are connected to one another by hollow passages. The lightguide may be optically coupled to a light source, and the viscoelastic layer and the nanovoided polymeric layer may be used in conjunction with the lightguide to manage light emitted by the light source. The viscoelastic layer may be a pressure sensitive adhesive.

Abstract: Self illuminated back and front lit signage for a printed graphic. The signage includes a turning film having a structured surface for redirecting light oriented on a first axis, a diffuser providing for diffusion, and a printed graphic oriented on a second axis. The first and second axis differ by at least 5°. The turning film receives light from an ambient light source and directs the light via the structured surface toward a viewer of the graphic in order to passively illuminate the signage.

Abstract: Self illuminated back and front lit shaped and two-sided signage. The signage includes a turning film having a structured surface for redirecting light and a diffuser providing for diffusion. The shape of the signage from a viewer's perspective provides the content, such as letters, to be conveyed to the viewer. Two-sided signage includes two signs arranged back-to-back, each including a turning film having a structured surface for redirecting light, a diffuser providing for diffusion, and a printed graphic. In the two-sided signage, the turning films receive light from an ambient light source and direct the light via the structured surfaces toward viewers of the two graphics in order to passively illuminate the signage. The two-sided signage can be shaped to provide content via the shape and graphics.

Abstract: This disclosure describes co-extruded multilayer articles including at least one continuous layer and one discontinuous layer, as well as systems and techniques for the manufacture of co-extruded multilayer articles. For example, a co-extruded multilayer article is described that includes a body having a plurality of layers, where a first layer of the plurality of layers is formed from a first material and is continuous along a longitudinal axis of the body, and a second layer of the plurality of layers is formed from a second material and is discontinuously co-extruded along the longitudinal axis.

Abstract: The present disclosure relates to articles and methods of sealing light redirecting film constructions comprising a microstructured optical film, such as a daylight redirecting film, bonded to another film. This type of assembly may serve various purposes. For example, the assembly may protect the structured film, provide additional functionality, such as diffusion or infrared reflection, and/or facilitate attachment of the microstructured optical film to a mounting surface, such as a glazing or window pane. The methods for sealing the edge of a light redirecting construction inhibit ingress of water and other contaminants during the film installation and afterwards during its regular use.
